MANUAL TRANSFER SWITCH
This unit is equipped with a manual transfer switch mechanism
that is comprised of two (2) circuit breakers. The load termi-
nals of each breaker are connected together to supply the load.
A mechanical, sliding bar interlock is provided to isolate the 2

transferring the customer load between the NORMAL (UTILITY)
power source and the Generator supply connected to the Cam-
Lok™ connectors (Figure 1).
